The system was implemented to streamline Destiny’s economy, according to Bungie. The Speaker, a major story character, will be the gateway for the exchange process. Players can take materials such as Ascentdant Shard, Ascendant Energy, Motes of Light, Glimmer, and more can be traded on a 1:1 basis for a small Glimmer fee, or sold to the NPC.

NPC Eris Morn, who was introduced in The Dark Below expansion, can exchange only Radiant materials obtained in the Destiny Raid called Crota’s End. The Speaker not only exchanges all of the material, but his ability to do so doesn’t appear tied to a reputation level requirement.
